I'm looking for an electrical coupling to provide 120VAC
to equipment on a rotating platform. The platform can
only turn one way, so it can't have wires up the hub.
Is there a commercial product out there, and if so, what
is it called? None of the electrical places I talked to
knew of anything like this...
You said "the platform can only turn one way, so it can't have wires
up the hub."
this sentence is unclear.......turning one way does not preclude
putting wires up through the hib
Does the platform do continuous 360's? Like display platform? Like
the turret in a tank?
If yes, you need a "slip ring"
These are very seldom used & most elctrivcal house's won't stock thme
Slip rings are used all over the place. They are very, very common, but
they are not a typical "off the shelf" item in most cases. The Thomas
Register lists some companies that make them commercially, but they're
fairly high end and expensive.
In many cases the company or person making the item that needs the slip
rings makes the slip rings as well as they are pretty simple. Any
electric motor shop will have a nice assortment of carbon brushes you
can use and probably brush holders as well.
I built a display carousel that needed to couple 12VAC power across the
rotary connection and I built the slip rings from a couple segments of
brass plumbing pipe mounted on PVC pipe with carbon brushes from an auto
parts store pressing on them.
It's called a slip ring, sometimes called a commutator ring (a commutator
ring is a specialized type of slip ring.)

They are called slip rings. There are a number of designs, but typically
it's a couple rings of brass with carbon brushes that press against them
to conduct the electricity. They are used on everything from tank
turrets to ferris wheels. Very similar to the commutator on a DC motor,
but the rings are not segmented and provide a continuous connection.
